Optional: If the granularity of data is known or can be inferred, this can be used to quantify the accuracy of digitization. For example, the variable “age” may have been recorded as integers. If most recorded numbers are close to an integer, the distance can be used to approximate the precision in digitization. If applicable, create a new column for the recorded variable, rounded to the appropriate precision. Then create another column and calculate the absolute difference between the recorded numbers and the rounded numbers. Add the mean, range, and standard deviation of the absolute difference to the ReadMe.
